P-58: Which Novel Sperm Selection is Suitable for ICSI? MACS-DGC or DGC-MACS
Background: Super-paramagnetic annexin-V conjugated micro-beads are able to eliminate sperm with phosphatidylserine externalization (PSE). PSE is considered as apoptotic sperm. PES positive sperm can be removed from sperm preparations sample to enhance sperm quality for assisted medical procreation. Therefore, the efficiency of this technique over normal sperm processing procedure such as densi...
متن کاملTriple touch sperm immobilization vs. single touch sperm immobilization in ICSI - a randomised trial
BACKGROUND Although different techniques for sperm immobilization have been described, their value has not been assessed in an adequately powered randomized study. The aim of this study was to compare two types of sperm immobilization methods prior to ICSI and to test the hypothesis that triple touch immobilization (TTIm) would lead to a higher (5% -65% up to 70%) fertilization rate (FR) than s...
متن کاملHyaluronan-binding system for sperm selection enhances pregnancy rates in ICSI cycles associated with male factor infertility
OBJECTIVES The aim of the present study was to compare two procedures for sperm selection in ICSI cycles - conventional morphology sperm selection (ICSI-PVP) and chemical selection through Hyaluronan-treated petri dishes (PICSI), when male factor was associated. METHODS The evaluated parameters were semen quality, fertilization and cleavage rates, chemical and clinical pregnancy rates, as wel...
متن کاملICSI significantly improved the pregnancy rate of patients with a high sperm DNA fragmentation index
OBJECTIVE Correlations between semen parameters and sperm DNA fragmentation index (DFI) were investigated to identify characteristics of sperm without DNA damage that could be used in selecting sperm for intracytoplasmic sperm injection (ICSI). Pregnancy outcomes were compared to determine whether in vitro fertilization (IVF) or ICSI is a better choice for patients who have sperm with a high-DF...
